Hi everyone,
I'm a new member of diyAudio, not an audio expert at all but an audio lover, in search of suggestions about the right speakers choice for my stereo set-up...
I own Marantz PM8000 95W-Amplifier + Marantz CD67-OSE CD Player + Boston VR3 tower speakers (back bass-reflex port).

I considder MonsterCable Z2 as a good reference.

I auditioned the Davis speakers (just the 17 KLV 6A model) and I find the sound is trasparent and slightly tending to the bright side (good thing to be put to work together with Marantz stuff). I'm more convinced after your suggestion, thanks a lot.
